-CQNTROELING MEANS; FOR nLncrmc-Ar. .onu'ron nnrvmo mE'cEAms To all wlwm concernia Be it known that I, ABRAM P. STEGKEL, a

citizen of the UnitedStates, residing at Buffalo', in the county of Erie and State of New York, have inventeda new and useful Im-. provernent in- Controlling Means for Electrical Clutch Driving Mechanisms, of which the following is a specification.

This invention relates to controlling]nea'nsv for mechanisms which include two. electric induction clutchesand aroused for starting,

. stoppingand reversing the motion of a ma- 1 chine or-element which 1s driven from an cle 1nent that1 'runs continuously in one direction": Q J The invention is especially desirable for Y use with1levators and hoistingflmachinery where several-'drives are-operated from the same continuously running line shaft, but is also applicable to other machinery, such, for mstance,- as metal planets and rolling mills,

- in which a part has. to be driven in opposite directions. and frequently started; stopped a and reversed. r

I The objects" QfEt-he invention. are to provide means whereby when the poweris out off from the driven member and it is'coast ing,- one or thebther clutch will act to o pose he coasting motion so asto gradual y arrest the motion'of thedrivenelementland bring it to a stopgently andwithout'shock';

alsoto provide-a rake for the drivenelement which isoperatediri conjunction with the clutches in such manner that it" s up plied. only to hold the driven element st'ationary after the motion'there of has been ar rested by the action of the, cli 1tches,whereby the driven elemerrtvis-s top'ed more'g'ently and, ispsecurely-held an .the wear on the brake is greatly reduced; also to provide a switch and connections which operate autobring the driven matically t6 excite either clutch for opposing motion previously set up by the other clutch only when the current has been 'cut 05 from such other clutch and the'driven element is coasting and only long endu'gh to ement' torest also to im prove clutch driving mechanisms of the character stated in the respects hereinafter described and set forth in the claims.

a and a driven memb 'r b. The clutches are of-thatsort in whicl' -one member; as]; of'

each clutch, carries a'con'ducting ring of located between electro-magnet poles b on; the

other f rn'ember, so that any relative motiontween the clutch members sets up currents in the conducting ring which tendto cause the driven mem-berto rotate with the 'driv- "2 member when the" latter is driven and to I stop when' the driving member isarrested.

A brake is preferably employed for hol ingthe driven element stationary afterit has been arrested by the action of, the clutches. Anordinary band brake-is shown consisting 1 of a friction band iwhich passes around a flange on the drum and is operated bya weight or equivalent device z'fl-and an electro-magnetic device I. When current passes through, the magnet I it lifts the weight and releases'the brake, and when'the current is interrupted the weight drops and applies the brake. Any suitable electrically-controlled brake can be employed. \Vhile a brake is preferably used it is not essential. to the operation of the mechanism, as will later ap-' pear.

The brake is not essential to the described action of the clutches and it can be omitted if desiredwithout changing the construction or operation of the mechanism. Y

Means different from those described can :be employed to produce the reversing action of the clutches only when the operating "switch is open. For instance, as shown in .Fig. 3, the revolving disk N cooperates with a pendulous electro-m'agnet N having a winding-adapted to-be connected across the main circuit by conductors g g, one of which leads to a contact farraiiged tobe engaged by the lever otthebperating switch M when it is opened. The switch magnet N is only energized when the operating switch is opened, to cut otf the power, and the mechanism is coasting. One of the conductors g g for energizing the magnet N forinstance, the conductor [,is connected to the core of the magnet N at 9' so that when the magnet is moved against one of the contacts nn a circuit is completed through one or the other of the clutches 1, 2, as before. The pendulous elect-ro-magnet makes the relay P, un-' necessary. The auxiliaryswitch-in this construction operates in the same manner as the other to produce the reversing action of the clutches.
